wAToH-MovEMENT.

SPECIE'ICATION forming part of Letters Patent No. 323,777, dated August 4, 1885.

Application filed August 16, 1884. (No model.)

To all whom it may concern:

Be it known that I, ALBERT D. BlNGl-IAM, of New Haven, in the county of New Haven, and in the State of Connecticut, have invented certain new and useful Improvements in Vatch-Movements; and I do hereby declare that the following is a full, clear, and eXact description thereo'f, reference being had to the accompanying` drawings, 1n which- Figure l is a plan view from the rear side of a watch-movement containing myimprovements, the back plate being removed. Fig. 2 is a like lview of the same from the front side, the dial and mainspring being removed. Fig. 3 is a plan view of said niovement from the rear with all of the train removed except the main wheel and the dial-wheels with their bridge. Fig. 4 is a perspective view of the intermediate dial-wheel with its bridge separated from the other parts of the train. Fig. 5 is a like view of the Cannon-pinion, hourswheel, and main wheel, and arbor separated from each other, and Fig. 6 is an enlarged section upon line 00 w of Fig. 3.

Letters of like name and kind refer to like parts in each of the figures.

My invention is an improvenient upon a watch-niovement which was patented December 27, 1881, No. 251,532, and has for its obusual dial-wheels, whereby I ani enabled to set said hands in the ordinary mannerinstead To this end my said invention consists in tion of parts as hereinafter specified.

In the annexed drawings, A represents the front or pillar plate of a watch, which is connected with a back plate by pillars -B or in any usual and well-known nianner. Said pillar-plate has the whole of its front side recessed for the reception of a mainspring, O, and within its center is journaled an arbor,D, that upon its front end is provided with a spring-collet, (Z, and upon its rear end has a toothed wheel, d', through which. the power of the spring is communicated to a time-train of usual construction and arrangement.

The arbor D is hollow, and within the same is loosely journaled the sleeve e of an hourshand wheel E, which latter is placed immediately in rear of the main wheel d', with said sleeve extending forward a sufiieient distance to' enable an hours-hand, F, to be placed upon its end in the usual manner.

Journaled loosely within the sleeve e is a cannon-pinion, G, which, at its outer end, is adapted to receive a minutes-hand, F', and axially to receive the arbor h of the center or minutes-wheel, H, said arbor being held in engagement with said Cannon-pinion by friction in the usual inanner. The cannon-pinion G and hours-wheel E have the usual relative proportions, and are connected by means of an intermediate dial-wheel, I, and pinion ,which latter are rigidlT connected together, and are journaled upon the inner side of a supplemental bridge, K, that is secured upon the lower face of the pillarplate A. rllhe bridgeK extends over the end of the cannonpinion G, and serves to hold the same and the hours-wheel E in position. The center-wheel arbor h passes 4through said bridge, which thus operates as a a journal-bearing for the front portion of the same.

The center wheel being connected with the time-train, the minutes and hours hands are driven in the usual manner, and in setting said hands a changein the position of the former is instantly communicated to the' latter. The arrangement of the dial-wheels below the pillar-plate enables their use without increase in the thickuess of the movement, as the space occupied by them and by the bridge in no manner interferes with the other operative parts of the train.

Having thus fully set forth the nature and inerits of my invention, what I claim as nexv 1s- 1. In a watch-movement, the dial-wheels driven from the minutes-arbor through frietional connection therewith, and having the Cannon-pinion and the sleeve of the hourswheel journaled axially lwithin and passing through the mainsprilig-arbor, substszntiall y as and for the purpose set forth.

2. In a watch inovement, in combination with the dial-wheels placed innnediately below the front or pillar plate, the minutes-arbor, a frictional connection between such arbor and Wheels through which the Wheels are driven from the arbor, and the sleeve for the hours- IOO hand, and the burrel of the eaunonpiniou for I In estilnony that I elam the fol'egoing I 1118 miuutesmnd passing forward xiully have hel'eunto set my hand this 1th day of through the mainspring', Substuntially as :md August, 1884-. vfor the Purpose deserbed.
